Psychocardiological impact of depression on medication adherence, ventricular function, and readmission in heart failure: A retrospective cohort study

Figure 2 Distribution of cardiovascular event readmissions in 1-year follow-up. This pie chart illustrates the proportion of different cardiovascular-related causes of hospital readmission (n = 48 events) among heart failure patients during the 12-month follow-up. The most frequent cause was worsening heart failure (54.1%), followed by acute coronary syndrome (myocardial infarction + unstable angina; 18.8%), arrhythmia-related hospitalization (14.6%), sudden cardiac death or major adverse cardiovascular events (8.3%), and other cardiovascular causes (4.2%). MACE: Major adverse cardiovascular events; HF: Heart failure; MI: Myocardial infarction; UA: Unstable angina.
